Water cooled exhaust

[rustygold]

Has anyone seen water cooled exhaust on theis 7.3? I gave seen bigger trucks have them to help EGT'S. Thought if it was out there maybe it could help us.

Lol
Water cooled exhaust doesn't help squat. Who cares if the exhaust is cold, if you're still melting pistons?

Do you mean water injection into the engine?

there most certainly is water logs for our engines, mostly for marine applications.

Nope my 12.7 detroit has water cooled exhaust system. HD trucks have them.

According to Detroit 60 series literature, only marine engines have water cooled exhaust.
Show us pictures then.

I'll take some tomorrow or find my book on the bus

Are you talking about misting water in to the intake to drop egts?

Water cooled exhaust is pointless really. EGTs start in the combustion chamber, make there way into the turbo, then out the exhaust system. You want to watch the EGTs to not only avoid turbo damage, but to also avoid melting pistons or doing head damage. You could do it to avoid killing the turbo but then you're only lying to yourself when you could still destroy the pistons. IMO, Skip it. Yes heavy trucks have it. They also have heavier duty engines and are running 100% duty cycle.
Now misting water into the intake might work. Would cut down on carbon build up in theory.

Are you talking abut circulating engine coolant through the castings, not actually into the combustion gases?

Ok so water cooled is only good for turbo so it doesn't over heat but other then that it's pointless

So is it a water cooled turbo?
I'm interested to see what you find in the manual.

New VW TSI's (gas) have the exhaust manifold integrated into the head (turbo literally bolts to the head), so they are water cooled now. My guess is it helps turbo heat soak, if you have extended high EGT's.

I could see this on larger engines, that can control the heat of the piston by cooling with large amounts of oil or the use of monotherm steel pistons that can handle heat. Now given the pistons can take higher heat, the turbo is going to need protection.

this thread makes me want to put an IDI in a boat
